DETAILED DESCRIPTION

[0055] In order to make the purpose, technical solution and advantages of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0056] Please also see Figure 1-Figure 6 , the present invention provides some embodiments of a floor scrubber with an automatic cleaning trash bin.

[0057] like Figure 1 , Figure 4 and Figure 6 As shown, the floor scrubber 1 with automatic cleaning trash can of the present invention comprises:

[0058] A housing 10, wherein the bottom of the housing 10 is provided with an opening;

[0059] A roller 70 is disposed in the opening;

[0060] A clean water tank 80, disposed on the housing 10;

[0061] A water pump 90, wherein the water inlet of the water pump 90 is connected to the clean water tank 80;

[0062] A trash bin 50 is disposed on the housing 10 and located on the side of the drum 70;

[0063] The trash can 50 comprises:

[0064] bottom wall 51;

[0065] The first side wall 52 and the second side wall 53 are disposed on the bottom wall 51 and are located on two sides of the drum 70 respectively;

[0066] A first rear wall 54, disposed on the bottom wall 51;

[0067] A horizontal wall 55, disposed on the first rear wall 54;

[0068] A second rear wall 56, disposed on the horizontal wall 55;

[0069] A top wall 57 connected to the second rear wall 56;

[0070] Wherein, there is a gap between the top wall 57 and the horizontal wall 55;

[0071] The bottom wall 51 is provided with a discharge port 511 , and the discharge port 511 is provided with a discharge door 512 ;

[0072] The horizontal wall 55 is provided with a cleaning nozzle 551 . The cleaning nozzle 551 is communicated with a water outlet of the water pump 90 , and the cleaning nozzle 551 faces the top wall 57 .

[0073] Specifically, the drum 70 refers to a cylinder for cleaning the floor, and the drum 70 usually cleans the floor by rolling. The trash can 50 refers to a box for collecting sewage for cleaning the drum 70 when or after the drum 70 is working. The clean water tank 80 refers to a box for storing clean water. The water pump 90 refers to a device for providing power for clean water. The housing 10 refers to a device with a accommodating cavity formed inside, and the housing 10 includes: a horizontal housing 11 and a vertical housing 12 connected to each other. The drum 70 and the trash can 50 are located in the horizontal housing 11, and the clean water tank 80 and the water pump 90 are located in the vertical housing 12.

[0074] When the trash bin 50 needs to be cleaned, the clean water in the clean water tank 80 is output to the cleaning nozzle 551 through the water pump 90. Since the cleaning nozzle 551 faces the top wall 57, the clean water sprayed from the cleaning nozzle 551 is sprayed toward the top wall 57, spreads around, and is evenly distributed in the gap. Since it is blocked by the second rear wall 56, the first side wall 52, and the second side wall 53, it is helpful for the clean water to be evenly spread in the gap. The clean water finally flows down from the first rear wall 54 to the bottom wall 51 and is discharged from the discharge port 511. Since the clean water sprayed from the cleaning nozzle 551 is evenly spread and then flows down along the first rear wall 54, it is conducive to the full cleaning of the first rear wall 54.

[0075] It can be understood that since the gap between the top wall 57 and the horizontal wall 55 is located at a higher position and the height of the gap is relatively small, it is not easy for garbage, dust and other debris to enter the gap. Even if it enters the gap, it is easier to clean the debris in the gap due to the higher speed of the clean water just out of the cleaning nozzle 551.

[0076] In a preferred implementation of the embodiment of the present invention, Figure 4 As shown, the preset height range is 5 mm to 20 mm. Specifically, the height of the gap is set according to the need. When the preset height range is 5 mm to 20 mm, it is beneficial to spread the clean water and provide a sufficient amount of clean water.

[0077] In a preferred implementation of the embodiment of the present invention, Figure 3 and Figure 6 As shown, the floor scrubber 1 with automatic cleaning trash bin also includes:

[0078] A sewage collection tank 58 is provided on the top wall 57;

[0079] The sewage collecting tank 58 is used to collect the sewage on the drum 70.

[0080] A through hole 581 is provided on the wall of the sewage collecting tank 58 facing away from the first rear wall 54 .

[0081] Specifically, the sewage collecting tank 58 refers to a tank body for collecting sewage on the drum 70 when the drum 70 is working. The sewage collecting tank 58 collects the sewage on the drum 70 in the sewage collecting tank 58. Of course, the sewage in the sewage collecting tank 58 can flow out from the through hole 581 and fall into the trash can 50.

[0082] The floor scrubber 1 with automatic cleaning trash can also includes:

[0083] The valve body 43 is disposed on the housing 10 and communicated with the sewage collecting tank 58;

[0084] A sewage tank 20 is disposed on the housing 10 and communicated with the valve body 43;

[0085] The air pump 60 is disposed on the housing 10 and communicated with the sewage tank 20 .

[0086] Specifically, the valve body 43 refers to a device for controlling the opening and closing of a channel. The sewage tank 20 refers to a box for carrying sewage. The air pump 60 refers to a device for providing power for gas.

[0087] When the floor scrubber 1 is working, the drum 70 rolls, and under the suction of the air pump 60, the sewage collecting tank 58 collects the sewage on the drum 70 and flows into the sewage tank 20 through the valve body 43. When the floor scrubbing is completed, the valve body 43 and the air pump 60 can be closed, and the sewage is stored in the sewage tank 20. When the floor scrubber 1 is not working, the sewage in the sewage tank 20 can be discharged. Specifically, the sewage discharge door and the valve body 43 can be opened, and the sewage in the sewage tank 20 is discharged from the valve body 43, enters the sewage collecting tank 58, and falls into the trash can 50 from the through hole 581, and is finally discharged from the sewage outlet. In this way, the automatic collection and discharge of sewage are realized.

[0088] It is understandable that the floor scrubber 1 can be used in conjunction with the base station 2. The base station 2 refers to a device that provides services for the floor scrubber 1, including sewage discharge services, clean water addition services, and cleaning of the sewage tank 20. The floor scrubber 1 is placed on the base station 2, and the sewage in the floor scrubber 1 can be discharged into the base station 2, and the clean water in the base station 2 can be added to the floor scrubber 1, so that the floor scrubber 1 can further scrub the floor. If the floor scrubber 1 does not need to scrub the floor further, the sewage tank 20 can be cleaned.

[0089] The housing 10 is provided with an avoidance groove, and the discharge door 512 is rotatably connected to the housing 10. The first end of the discharge door 512 closes the discharge port 511, and the second end of the discharge door 512 covers the avoidance groove. The base station 2 is provided with a door-pushing protrusion. When the floor scrubber 1 is placed on the base station 2, the door-pushing protrusion pushes the second end of the discharge door 512 so that the second end of the discharge door 512 is pushed into the avoidance groove, and the discharge door 512 opens, and the sewage in the trash can 50 can be discharged from the discharge port 511. The base station 2 can be provided with a water storage tank 4 for storing sewage, and the sewage in the trash can 50 can be discharged into the water storage tank 4.

[0090] The sewage tank 20 and the air pump 60 can be connected through a three-way valve. The three-way valve refers to a valve with three ports. The three ports of the three-way valve can be all closed, all opened, or only any two of the ports can be opened, and the remaining port can be closed. For example, the sewage tank 20 is connected to the first end of the three-way valve, the air pump 60 is connected to the second end of the three-way valve, and the third end of the three-way valve is connected to the outside. When it is necessary to pump sewage, the first and second ends of the three-way valve are opened, and the air pump 60 is started for suction. When it is necessary to discharge the sewage in the sewage tank 20, the first and third ends of the three-way valve are opened, and the outside air is replenished into the sewage tank 20 to balance the decrease in air pressure caused by the reduction of sewage in the sewage tank 20.

[0091] In a preferred implementation of the embodiment of the present invention, Figure 4-Figure 6 As shown, the floor scrubber 1 with automatic trash cleaning bin also includes:

[0092] A wiper strip 31 is disposed on the housing 10 and is located above the roller 70 and abuts against the roller 70;

[0093] A sewage channel 32 is provided in the housing 10;

[0094] Wherein, the wiper strip 31 is used to scrape off the sewage on the drum 70;

[0095] The sewage channel 32 is used to transport the sewage scraped by the wiper strip 31 to the sewage collecting tank 58;

[0096] The sewage channel 32 is located above the through hole 581 .

[0097] Specifically, the wiper strip 31 refers to a component for scraping off the sewage on the drum 70, and the sewage channel 32 refers to a channel for the sewage to flow. The wiper strip 31 scrapes off the sewage on the drum 70, and the sewage flows into the sewage collection tank 58 from the sewage channel 32. Since the sewage channel 32 is located above the through hole 581, when the sewage in the sewage tank 20 is discharged into the sewage collection tank 58, it is preferentially discharged into the garbage tank 50 from the through hole 581, and will not flow back into the sewage channel 32, and will not flow back into the drum 70 to pollute the drum 70.

[0098] In a preferred implementation of the embodiment of the present invention, Figure 3-Figure 6 As shown, the floor scrubber 1 with automatic cleaning trash bin also includes:

[0099] The brush 59 has two ends rotatably connected to the first side wall 52 and the second side wall 53 respectively;

[0100] The ends of the bristles on the brush 59 abut against the roller 70 .

[0101] Specifically, the wiper strip 31 can scrape off the dirty water on the drum 70, and the brush 59 can scrub the drum 70. The ends of the bristles on the brush 59 abut against the surface of the drum 70, and the drum 70 can be scrubbed by rotating the brush 59. The drum 70 can be scrubbed by the brush 59 when the floor scrubber 1 is working, or when the floor scrubber 1 finishes scrubbing. The debris and dirty water scrubbed by the brush 59 will be collected in the trash can 50.

[0102] In a preferred implementation of the embodiment of the present invention, Figure 4-Figure 6 As shown, the end of the bristles at one end of the brush 59 abuts against the first side wall 52 , and the end of the bristles at the other end of the brush 59 abuts against the second side wall 53 .

[0103] Specifically, the first side wall 52 and the second side wall 53 may also be cleaned by the brush 59 . When the brush 59 rotates, the first side wall 52 and the second side wall 53 are brushed.

[0104] In a preferred implementation of the embodiment of the present invention, Figure 4-Figure 6 As shown, the ends of the bristles on the brush 59 abut against the wall of the sewage collecting trough 58 facing away from the first rear wall 54 .

[0105] Specifically, since the sewage in the sewage collecting tank 58 may flow into the garbage bin 50 from the through hole 581 , debris may be attached to the outside of the tank wall on the side where the through hole 581 is located, and the tank wall may also be scrubbed by the brush 59 .

[0106] In a preferred implementation of the embodiment of the present invention, Figure 5 As shown, there are two cleaning nozzles 551 , which are respectively located on the horizontal wall 55 close to the first side wall 52 and the second side wall 53 .

[0107] Specifically, in order to further ensure that the corners of the trash bin 50 are cleaned quickly, two cleaning nozzles 551 are provided, and are close to the two corners of the trash bin 50. The corners are cleaned by the cleaning nozzles 551, which is conducive to fully cleaning the trash bin 50.

[0108] In a preferred implementation of the embodiment of the present invention, Figure 5 As shown, the first rear wall 54 includes:

[0109] A first curved surface portion 541, a straight surface portion 542, and a second curved surface portion 543 connected in sequence;

[0110] Wherein, the first curved surface portion 541 is connected to the first side wall 52;

[0111] The second curved surface portion 543 is connected to the second side wall 53;

[0112] The first curved surface portion 541 protrudes toward the center of the trash bin 50;

[0113] The second curved surface portion 543 protrudes toward the center of the trash bin 50 .

[0114] Specifically, in order to reduce the accumulation of debris in the trash bin 50 in the corners and make it difficult to clean, a protruding structure is provided at the corners to increase the angle between the two adjacent surfaces, so that clean water can flow through the protruding structure more easily and debris is not easily accumulated. In the present application, the first rear wall 54 has a first curved surface 541 and a second curved surface 543 at both ends. Due to the existence of the first curved surface 541 and the second curved surface 543, debris is not easily accumulated in the corners, and clean water is also more likely to flow into the first curved surface 541 and the second curved surface 543 to fully clean the debris. The two ends of the first curved surface 541 are smoothly transitioned with the straight surface 542 and the first side wall 52, respectively, and the two ends of the second curved surface 543 are smoothly transitioned with the straight surface 542 and the second side wall 53, respectively. The use of a smooth transition method can further improve the ease of cleaning debris.

[0115] In a preferred implementation of the embodiment of the present invention, Figure 5 As shown, the horizontal wall 55 includes:

[0116] A first protruding portion 552, a main body portion 553 and a second protruding portion 554 connected in sequence;

[0117] Wherein, the first protruding portion 552 is connected to the first curved portion 541;

[0118] The second protruding portion 554 is connected to the second curved portion 543;

[0119] The two cleaning nozzles 551 are respectively disposed on the first protruding portion 552 and the second protruding portion 554 .

[0120] Specifically, since the first rear wall 54 has a first curved surface 541 and a second curved surface 543, a first protrusion 552 and a second protrusion 554 are correspondingly provided on the horizontal wall 55. The first protrusion 552 is extended from the main body 553 to the center of the trash bin 50 and the second protrusion 554 is extended from the main body 553 to the center of the trash bin 50. The first protrusion 552, the main body 553 and the second protrusion 554 are located in the same plane. A cleaning nozzle 551 is provided at a position where the first protrusion 552 is close to the first curved surface 541, and another cleaning nozzle 551 is provided at a position where the second protrusion 554 is close to the second curved surface 543. After the clean water outputted by the cleaning nozzle 551 rushes toward the top wall 57, part of the clean water will directly fall downward to wash the connection between the first curved surface 541 and the bottom wall 51, and the connection between the second curved surface 543 and the bottom wall 51.

[0121] Based on the floor scrubber 1 with an automatic trash bin cleaning device described in any of the above embodiments, the present invention further provides a preferred embodiment of a floor scrubber system:

[0122] like Figure 1-Figure 3As shown, the floor scrubber system of the present invention comprises: a floor scrubber 1 with an automatic cleaning trash bin as described in any one of the above embodiments and a base station 2.

[0123] Based on the floor scrubber with an automatic trash cleaning bin described in any of the above embodiments, the present invention also provides a preferred embodiment of a control method for a floor scrubber with an automatic trash cleaning bin:

[0124] The control method of the floor scrubber with automatic trash cleaning bin according to the embodiment of the present invention comprises the following steps:

[0125] Step S100: When the discharge door is opened, the water pump is controlled to start, and the clean water in the clean water tank is transported to the cleaning nozzle to clean the garbage bin.

[0126] Specifically, when the floor scrubber stops working, the trash can can be cleaned. Usually, the trash can is cleaned with the discharge door opened, and the cleaned debris is directly discharged through the discharge port.

[0127] Step S200: When the discharge door is opened, control the brush to clean the drum.

[0128] Specifically, when the floor scrubber stops working, the drum can be cleaned by controlling the brush to rotate. Since the ends of the bristles on the brush abut against the surface of the drum, the drum can be scrubbed when the brush rotates. Of course, the bristles of the brush can also abut against the first side wall, the second side wall or the wall of the sewage collection tank, and can also scrub the first side wall, the second side wall or the wall of the sewage collection tank.

[0129] It should be understood that the application of the present invention is not limited to the above examples. For ordinary technicians in this field, improvements or changes can be made based on the above description. All these improvements and changes should fall within the scope of protection of the claims attached to the present invention.
